Test Suite Validation Skill

This skill helps you efficiently validate code changes by running the appropriate subset of the test suite. It uses scripts/run-tests to intelligently discover affected tests and run only what's necessary for validation.

When to Use This Skill

Use this skill when you have:

• Made changes to source code files and want to validate they work
• Fixed a bug and want to verify the fix
• Added a feature and need test coverage
• Modified test infrastructure or configuration
• Want to verify changes don't break existing functionality

Key Principles

1. Always use the run-tests skill when testing code changes - it's optimized for intelligent suite discovery
2. Never run pytest directly - bypasses the project's test infrastructure (use scripts/run-tests or riot via scripts/ddtest)
3. Minimal venvs for iteration - run 1-2 venvs initially, expand only if needed
4. Use --dry-run first - see what would run before executing
